countMissing            Count the number of missing landmarks in an
                        array
covar                   Calculate covariance matrix between individual
                        landmark coordinates
dotcorr                 Calculate 3D vector correlation matrix using
                        the congruence coefficient. Skips any missing
                        values in computation of correlation matrix
dotcvm                  Calculate 2d or 3D covariance matrix using
                        unscaled congruence coefficient.  Skips any
                        missing values in computation of covariance
                        matrix
mirrorfill              Fill missing symmetrical landmarks for all
                        specimens in an array using mirrored values
                        from other side of a bilaterally symmetrical
                        object where present
mirrorfill1             Fill missing landmarks for a single specimen
                        using mirrored values from other side of object
plotSpecimens           Plot an array of specimen landmark data in an
                        interactive 3D frame
procrustes              Conducts Procrustes superimposition to align 3D
                        shapes with or without scaling to centroid
                        size.
